Most of the enzymes are
Detailed Explanation:
Enzymes are biological catalysts that accelerate chemical reactions in living organisms, and the vast majority are proteins. They possess specific three-dimensional structures formed by amino acid chains, enabling them to bind substrates and facilitate reactions.
While a few enzymes are ribozymes (RNA-based), over 99% of all known enzymes are proteinaceous. Lipids, acids, and alkalis serve other biological functions but do not constitute enzyme structure.
Therefore, proteins form the structural basis of most enzymes, making Option 4 the correct answer.
